Bugs
The app is wonderful, it trains us on memory, speed, it has a metronome, the music pieces sound great but I have one problem about it, only one. The metronome kinda just stops working after using it for a few minutes, and I have to reinstall the app to make it work again. I was planning to buy a level but I’m afraid that after I buy it the metronome will disappear again so I’ll be waiting if the developers ever decide to fix this.
